Application le'd March 18, 1910. Serial No. 550,238.

To all whom it may concern.'

Be it known that I, Gnoaon F. ECKART, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Skates; and I do hereby declare the following to be a full, clear,

and exact description of the invention, such `as will enable others skilled in the art to which it appertains to make and use the same.

rll`his invention relates to a novel construction in a skate, the object being to provide a device of this character which is adjustable in length, is very strong and rigid and is convertible from a roller into an ice skate land vice versa, and consists 1n the features of construction and combinations of parts hereinafter fully described and claimed.

In the accompanying drawings illustrat-4 ing this invention: Figure 1 is a View in side elevation of a skate equipped with rollers constructed in accordance with my invention. Fig. -2- is a bottom plan` view of the same. Fig. --f is a central vertical longitudinal vsection of the same. Fig. -ftis .a rear end elevation of the same. Fig. -5- is a fragmentary plan view of the same showing-the latch Vfor securing the two parts of the skate togethel' against relative longitudinal movement. Fig. 1s-

a view in side elevation of the skate equipped is a bottom plan view of the same. Fig. -8- is a rear elevation of a modified form of construction in which a single pair of centrally disposed runners are employed. Fig. -9- is a view similar to Flg. e8- showing a roller substituted for the runner shown 1n the latter. Fig. 10; is a detail perspectlvevlew of a runner constructed m accordance with my invention. F ig. 11- is a view 'in side elevation partly broken away showing a roller constructed in accord ance with my invention. Fig. *12- is a diametric section of said roller.

.One of the main objects of my invention is to provide suitable means for rendering the skate extensible so as to lit feet of varying lengths.

A furtherparticular object of the 'invention is to provide means for rendering the skate suficlently stiff and rigid' to withstand the strains to which it is ordinarily subjected. j .t

Further objects of my' invention consist Specification of Letters Patent.

j said dished or olf-set Patented Aug. 16, 1910.

in certain details of construction whereby the same may be easily converted from an ice skate into a roller skate and vice versa. i

The skate consists of two parts each consisting ofa top plate 1 and 2-respectively,

supported upon rollers or runners which latter are mounted thereon in the manner here.- inafter described. The said top plates 1 and 2 are telescopically tted together at their Overlapping end portions. To this end the plate 2 is-provided with parallel straight side edges at its forward end portion which are received 'in t-he turned flanges 3 on the side edges of the plate 1.

elongated substantially rectangular dished guides formed by over- The' latter is provided with an portion adjacent its rear end and midway between its side edges and said plate 2 is similarly provided midway between its side yedges with a recesso extending longitudinally thereof and in which the said dished i or olf-set portion 4 of said plate 1 is adapted to be received and guided, said recess 5 of said plate 2 extending throughout the length of the tongue 6 at the forward end thereof.

In the bottom of said recess 5 isa series'of i openings 7 which are adapted to receive the free end portion of a latch pin 8 4disposed upon the free endY portion of a flat sprlng 9 secured to the lower` face of the plate lat one end and extending at its free end. into portion 4 through a slot in one end thereof, the bottom of said portion 4 being provided with an' opening 10 for the passage of said latch pin therethrough.y Said pin whenI passed through said last-named opening and one of sald first-named openings 7 will obviously serve to lock said plates l and 2 against relative longitudinal movement. Said pin is normally held by said spring 9 at the lower limit of its movement in the engaging relation described, said plates being released from relative engagement by ralsing said pin against the action of the spring carrying the same. Secured at its ends to said plate 1 and the free end portion of said tongue 6l lOl) thereof is a bowed stiening member 11 l provided midway between its ends with pro jections 12 bearing' upon the bottom of said plate 2 and provided midwayv between its4 side edges with "a longitudinalrib 13. Said member. 11 constitutes a truss to prevent yielding of said plate 2 to weight imposed thereon, and by the manner of enga ng said plate 1 with said plate 2 the stiienlng effect 3-is transmittedA to thevformer an obvious manner. v

Secured to each of said plates 1 and 2 at the free ends of its arms 14 is a U shaped member, the middle .portion 15 of which extends at an incline to the plane. of the plate to which it is secured, said members 14--15 of said respective plates being disposed in opposed relation to each other, that is, the middle portions or webs 15 thereof being ,oppositely inclined. .Each of the latter is equipped at. its higher end with a downwardly projecting flange 16 provided with an opening. Secured to said webs 15 of said members 14 are plates 17 each of which is provided with side flanges 18 between which a rubber springy 19 is confined. Said spring i is further confined between said plates 17 having and opposedv L-shaped plates 20 and 21 each a long and a short arm, the long arms thereof being riveted together. The short arms thereof are in contact with each otherand are provided with an opening through which a pivot pin 22 passes, the latter projecting through the opening in the flange 16 to pivotally secure said last-named` plates 20 and 21 toward said middle portions of said members 14 to maintain said 19 partially compressed. The said ate` 20 is provided with relatively long side ianges 25 bent to` inverted U-sliaped form, the outermost end portions 26 thereof being provided in their free end portions with recesses 27 in which the shafts 28 of the rollers 29 or bolts for securing the run- Lner frames are received as will be hereinaftei` more fully described. The said plate 21 isp'rovided with relatively short side lto fian es 30 which are bent downwardly to exten substantially atpright angles thereto and parallell with the end portions -26 and are similarly equipped with recesses 27 in their freeends to co-act with the recesses 27 28 or bolts as required.

previously mentioned to receive said shafts Separator sleeves 31 are interposed between the last-named of "said lower platies 21' and through saidfsleeves the said shaft 28 passes.

- The latter carries cups 32 for the reception of balls which are adapted to run into grooves33 ofthe hubs 34 of rollers. Thev latter consist of side plates 35 between which raw hide or other 4rims or tires 36 are secured. Each of said plates is provided between its center andjts periphery. with an annular off-set portion 37, the inner walls 38 in s 42 which 'only one of said of which form annular ianges which engage and confine the said hubs 34. A ring 3 9 of wood or terposed between said annular off-set portions 37 of said plates and serves'to support the middle portion of the rim or tire 36.

The rivets 40 securing said plates together pass through said rims or tires 36 to secure the latter. To further hold the same in place the peripheral edges of said plates are provided with annular sharp edges 41 which are adapted to bite into said rims or tires 31 to further securely hold the latter in place.

In the legs of the U-shaped flanges 25 of the upper plates 20 are two opposed openare adapted to receive pins 43 ad] acent the free ends of flanges 44 of plates 45 between which skate runners 46 are received and secured, said flan es 44 bein off-set outwardly from said p ates 45 an provided adjacent their lower ends. with openings 47 for the passage of bolts 48 by means of which and said pins 43 said runners 46 are secured to said U-shaped flanges in place of the rollers when it is desired to convert the skate froml a roller to an ice skate. In mounting said runners in place the said flanges 44 are sprung toward each other in order to enable said pins 43 to pass between thel opposing portion of said U- shaped flanges and spring'into the opening 42 in the latter. To prevent contraction of said ianges 44 after insertion of. the runners in place separator sleeves-49 are interposed between the saine through which said Vbolts 48 pass.

The skates are mounted upon the shoe of the wearer in the usual manner, the plates 1 being equipped with the screw actuated' clamping jaws 50 and the plates 2 being equipped with projections 51 having slots 52 for the passage of straps. l In Figs. -8- and -9- I have shown a modified form of construction in which each skate instead of being yequipped with two pairs of rollers or runners is equi ped with only one pair thereof, the latter eing centrally disposed relatively to the side edges of the plates 1 and 2. In this construction plates 20 or 2l need be einployed and the side flanges 53 of the latter bent downwardly in the same manner as the other suitable material is 1n-y flanges 30of the plates 20 shown in Figs. 2,

gree of strength of the top plate and without prohibitively increasing the weight of lthe .skatehas not to my knowledge been heretol deflected relatively to their normal positions `two relatively movable in alinement with each other so as to de scribe an arc in travel. This is, l believe, not novel in the art, but l believe that the specific means employed for readily converting the'skate from a roller to an ice skate and vice versa are novel.
